HOWVARD K. KING, OF PHILADELPHIA, PENNSYLVANIA, ASSIGN OR TO CHAMBERS BROTHERS COMPANY, A CORPORATION OF PENNSYL- VANIA.

FOLDING-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1905.

To all whom, it may concern.-

Be it known that I, HOWARD K. KING, acitizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Folding-Machine, of which the following is a specification.

My invention relates to improvements in folding machines, and comprises improved means for the arrangement of the carryingtapes so that pairs of said tapes may travel together one above the other in the same direction for conveying superimposed signatures.

My invention is especially useful in connection with what are commonly known as double-sixteen machines.

My invention comprises improved means for returning two or more of said tapes so as not to interfere with the operation of the machine.

Referring to the drawings, Figure 1 is a plan view of an ordinary folding-machine containing my improved means. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is avertical section on line 3 3 of Fig. 1. Fig. 4 is a vertical section on lines 4 4 of Fig. 3. Fig. 5 is a plan view of the mechanism shown in Fig. 4. Fig. 6 is a vertical section on line 6 6 of Fig. 5. Fig. 7 is a vertical section on line 7 7 of Fig. 5.

Similar numerals refer to similar parts throughout the several views.

The folding-machine shown in plan view in Fig. 1 is of the same general type as that shown in patents to me, Nos. 667,021 and 667,022, dated January 29, 1901, with the exception of the details herein described. In Fig. 1 the sheet is shown as having passed through the folding-rollers 1 and 2 and at the same time having been cut in two parts or signatures 3 and 4 by the cutter 5, as shown in Fig. 3, operating in the groove 6 of roller 1. The abutting ends of sheets 3 and 4 are shown separated by the bar 7. These signatures are now carried upon the tapes 8 in the direction of the arrow until their front edges encounter the stops 9. Signature 3 is struck through rollers 10 and 11, while signature 4 is struck through rollers 12 and 13. The signature 3 is delivered by rollers 10 and 11 to tapes 14, traveling in the direction of the arrow, (see Fig. 2,) while signature 4 is carried through rollers 12 and 13 and on tapes 15. The operations of the machine are so timed that a sig-' nature from rollers 10 and 11 will be delivered upon tapes 14 over a signature carried on tapes 15, delivered from rollers 12 and 13, so that said two signatures 3 and 4 will register when brought to rest against stop 45 over rollers 16 and 17, so that one signature will be folded or inset within the other. One of the objects of my invention is to provide means for supporting the tapes 14 and so that they will travel in the same direction close together and one above the other and so as to prevent any interference of the returning tapes with said signatures. This cooperation of tapes 14 and 15 secures a more complete control of the travel ofthe signatures and obviates the necessity for the use of separating-bars to prevent displacement of the signatures. At the same time the return of said tapes is secured in such a way as not to obstruct or interfere with the operation of the machine. As will be seen in Fig. 2, tapes 15 return about rollers 18, 26, 19, and 13, and tapes return about rollers 18, 26, 27, and 28 in the usual way. Tapes 14, however, are made to return about rollers 20, 21, 22, 23, and 12 between the severed sections or signatures 3 and 4 after the sheet has received its first fold.

The returning of the tapes 14 over the top of the machine is made possible by the fol lowing mechanism: Bar 7 is suitably supported to the stationary parts of the machine at one end by the bracket 29, secured by the setscrew 42, and at the other end by the bracket 30, secured by the set-screw 43. In this bar 7 are provided the apertures 31, through which the tapes 14 pass. To this bar 7 are secured the brackets 32 and 33, upon which are mounted the rollers 22 and 23, which serve to guide the tapes 14 through the apertures 31. At the end of the bar 7, which encounters the advancing sheets, are provided the deflecting members or extensions 34 and 35, 34 being integral with the supporting-bracket and 35 being secured to the bar by the rivets or bolts 36 or by any other suitable means. The end of bar 7 is also notched, as at 37, (see Figs. 5 and 7,) and is also provided with the guide channels or grooves 38 and 39 in said notch.

'The supporting guide-rod 40 is also provided in connection with bar 7, being held in position by the bracket 41, secured to said bar 7.

By the above-described mechanism it will be seen that when the sheet receives its first fold and is delivered through the rollers 1 and 2, cut into two separate signatures, the deflecting member 35 will encounter the under edge of signature 1 (see Fig. 3) and guide or deflect said edge along the top of deflector 35 to the top surface of bar 7 while the deflector 3 1 will encounter the upper side of the edge of signature 3 (see Fig. 6) and deflect it downwardly under bar 7. The rod 10 will serve to support the under side of said signature 3 as it travels under bar 7. The guiding grooves or channels 38 and 39 will insure the proper separation of said two signatures, so that they will not catch or stick, but will slide smoothly along the deflectors and be properly directed, as above described. It is obvious that as one signature moves along the top of bar 7 while the other moves beneath it and upon the other side thereof a space is maintained cleared for the travel of the tapes 14: through apertures 31 without any danger of interfering with said sheets.

What I claim is 1. In combination with a folding-machine, means for deflecting the abutting edges of traveling sheets one above and the other below the plane of said traveling sheets and tapesupporting rollers so positioned as to guide the tape through the space between said deflected edges.
